Check Digit Verification of cas no

The CAS Registry Mumber 1226859-18-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,8,5 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1226859-18:
(9*1)+(8*2)+(7*2)+(6*6)+(5*8)+(4*5)+(3*9)+(2*1)+(1*8)=172
172 % 10 = 2
So 1226859-18-2 is a valid CAS Registry Number.

Azodicarhoxamides vs. azodicarboxylates in reactions against thioisomuenchnones: 1,3-dipolar cycloaddition or nucleophilic addition?

Sanchez, Barbara,Lopez, Ignacio,Light, Mark E.,Silvero, Guadalupe,Bravo, Jose Luis

scheme or table, p. 1648 - 1652 (2010/06/16)

This communication presents the first study on the use of azodicarboxamides against mesoionic heterocycles as 1,3-dipoles. The reactions yield thioureido compounds. Their formation could be explained, on the basis of experimental results and preliminary theoretical calculations, by a nucleophilic addition followed by rearrangement; however, a formal 1,3-dipolar cycloaddition and subsequent fragmentation and rearrangement of the transient cycloadducts could not be ruled out. Reactions are carried out in refluxing toluene and are complete in 90-240 min. Structural elucidation of the products is based on single-crystal X-ray analysis, as well as other spectroscopic data and 2D-NMR correlations.
